I think that its in the brain. Our brain cannot function, and so those our whole body(except for the heart?), if it did not get blood that supplies oxygen.
oxyhemoglobin (hemoglobin bound to oxygen) is highest in the alveolar venule. This is the initial vessel carrying freshly-oxygenated blood away from the alveolus, which is the air-sac in the lung where gases are exchanged.
There are approximately 5 quarts of blood in the human body.
To calculate the number of red blood cells (RBCs) in the human body, you can use the average volume of blood in an adult (approximately 5 liters) and the typical concentration of RBCs, which is about 5 million cells per microliter. By multiplying the blood volume in microliters (5 liters = 5,000,000 microliters) by the average RBC concentration, you can estimate the total number of RBCs. This results in an approximate total of 25 trillion red blood cells in a healthy adult.
Blood volume and concentration are crucial for maintaining proper bodily functions. Blood volume ensures adequate circulation of nutrients, hormones, and oxygen to body tissues, while blood concentration regulates the balance of electrolytes, proteins, and cells in the blood. Changes in blood volume and concentration can impact blood pressure, hydration levels, and overall health.
The driving force behind gas exchange in the human body is the concentration gradient of gases such as oxygen and carbon dioxide between the alveoli in the lungs and the blood in the pulmonary capillaries. Oxygen moves from the alveoli into the blood, while carbon dioxide moves from the blood into the alveoli, driven by differences in their partial pressures.
The lungs of course
The highest concentration of mitochondria in the human body is found in muscle cells, particularly in the muscles used for endurance activities like the heart and skeletal muscles.
The pulmonary vein carries blood with the highest oxygen concentration, as it transports oxygen-rich blood from the lungs to the heart. This freshly oxygenated blood is then pumped out to the rest of the body by the heart.
The blood in the pulmonary veins contains the highest concentration of oxygen since it has just been oxygenated in the lungs before returning to the heart to be pumped to the rest of the body.
The total amount of oxygen in an average human body can be calculated by multiplying the volume of blood by the concentration of oxygen in the blood. Therefore, the total amount of oxygen in an average human body is 4.8 L x 0.0070 M = 0.0336 mol.
Pulmonary veins, as they carry freshly oxygenated blood from the lungs back to the heart for distribution throughout the body.

Water
The normal concentration of sodium chloride in human blood plasma is around 0.9% or 9 grams per liter. This concentration is important for maintaining proper hydration levels and osmotic balance in the body. Any significant deviation from this concentration can lead to health issues.
Blood pressure is highest in the arteries.
